A Key to open Heaven's Gate : Or, A ready path-way to lead men to heaven. Written and printed for the benefit of all true Christians to read and hear, and make good use of before it be too late. And therefore i advise every man and woman to give heed to what is spoken in this little book, and they will be sure to find mercy from Jesus Christ; who faith, ask and ye shall have, seek and ye shall find, knock and it shall be open unto yon. By the Reverend Dr. Gilbert.
